What is the “proper” proportion of a flag?
There is no single correct proportion for all flags; each flag has its own. There are a few general trends in flag proportions based on certain influential flag designs: flags based on the French flag copy its proportions of 2:3, German flags are 3:5, U.S. flags are 10:19, and Russian, Commonwealth of Nations, and communist flags use 1:2. Among national flags, Nepal’s irregularly shaped flag has the shortest proportions at 4:3 (in other words, longer down the hoist than along the fly), while Qatar uses the longest at 11:28 (though Iran once used a flag with the proportions of 1:3).
